The limitation of utility model.
As shown in Figure 1, it is the structural schematic diagram of coal dust jumbo bag open the bag device provided by the utility model, the coal dust jumbo bag
Open the bag device includes discharge bin 1, and discharge bin 1 has feed inlet 11 and discharge port 12, and feed inlet 11 is structure wide at the top and narrow at the bottom, so as to
It can smoothly enter into discharge bin 1 in jumbo bag 10, the discharging direction of discharge port 12 is communicated with venturi tube structure 8, venturi tube structure 8
One end be connected with blower 6, with guarantee wind powder mixing effect.
Specifically, it is equipped with support construction 2 and the logical material structure 3 in support construction 2 in discharge bin 1, leads to material structure 3 and wraps
Cutting member 31 and transition piece 32 are included, cutting member 31 is optionally to be made of much knives tool, and much knives have to form cone structure, such as
This can be conducive to the cutting of jumbo bag 10；Also optionally, the point of a knife as lance is set again on the top of much knives tool, for puncturing ton
Bag 10.Transition piece 32 is connect with cutting member 31 and support construction 2 respectively, and transition piece 32 is equipped with a plurality of channel that coal dust can be made to pass through
33, after jumbo bag 10 is cut by cutting member 31, coal dust is fallen into discharge bin 1 by transition piece 32, and jumbo bag is by transition piece 32 and support
Structure 2 supports, i.e., jumbo bag 10 (the especially polybag of liner) can then be blocked by transition piece 32 and support construction 2, cannot be with coal
Powder is fallen together to discharge port 12, to will not lead to the blocking in defeated powder channel.It should be noted that the cross-sectional area of transition piece 32
Want moderate, can neither it is too small can not be excessive, because of the too small gap for representing channel 33 also very little, then will result in coal dust not
With the discharging being well on from channel 33；The gap that channel 33 is represented if excessive is very big, then will result in inner lining plastic bag
Some broken plastic strips fall into the bottom of discharge bin 1 together by channel 33 and coal dust, in turn result in blocking.Preferably, transition
Part 32 up and down, and including a plurality of spaced tube body, forms channel 33, can so make between every two adjacent tube bodies
Transition piece 32 top and side can discharging, considerably increase the speed of discharging.
Specifically, support construction 2 be equipped with it is multiple coal dust can be made to pass through but the intransitable through-hole 21 of jumbo bag, so can be into
One step facilitates the discharge rate of coal dust, and by the through-hole 21 of setting certain pore size, it can not only realize support jumbo bag 10, but also can prevent
Some broken plastic strips or the biggish impurity of other volumes enter defeated powder channel.
Specifically, sealing structure is equipped at feed inlet 11, sealing structure includes the first sealing set on 11 periphery of feed inlet
Structure 41 and the second seals structure 42 below feed inlet 11, the first sealing structure 41, second seals structure 42, feed inlet
11, support construction 2 and logical material structure 3 form the cavity for accommodating jumbo bag.First sealing structure 41 is preferably steel plate, to prevent
Coal dust after entering cavity floats to the outside of discharge bin 1；Second seals structure 42 is preferably that steel plate is leaned on when carrying out discharging
Coal dust at nearly feed inlet 11 will receive the influence for the coal powder natural accumulation being disposed below, and gradually to heap at feed inlet 11
Product so that the diameter for the jumbo bag 10 being located at feed inlet 11 increases, and then contacts with second seals structure 42, forms self-sealing
Structure, so that the intracorporal coal dust of chamber further be made not float to the outside of discharge bin 1.Further, since the first sealing
The positional relationship of structure 41 and second seals structure 42 when coal dust discharging, can form vortex, i.e., least a portion of coal in the cavity
Powder can be flown upward upwards along the inner wall of discharge bin 1, after touching the first sealing structure 41 and second seals structure 42 (i.e. steel plate), meeting
It is slipped in discharge bin 1 naturally along steel plate.
Specifically, discharge bin 1 is taper (structure i.e. wide at the top and narrow at the bottom), and the side wall of discharge bin 1 and the angle of horizontal plane are greater than
The natural packing angle of coal dust, preferably greater than 60 °, so as to be conducive to coal dust after transition piece 32 along the inner wall of discharge bin 1 faster
Discharge port 12 is flowed to fastly, without there is a phenomenon where accumulate.
Specifically, the side wall of cavity is connected with dedusting structure 5, such as can be bag filter.The lower part of dedusting structure 5
It is connected to the side wall of cavity, dedusting structure 5 is equipped with air-introduced machine.When unpacking, which works, to be carried out, air-introduced machine is opened, in suction chamber body
The air in portion makes inside cavity form negative pressuren zone, prevents coal dust from flying upward away.Coal dust is filtered in dedusting structure 5, thus not
It can be discharged into the external environment, dedusting structure 5 is additionally provided with air back-blowing mechanism, can periodically blow the coal dust being adsorbed on cloth bag
It falls, drops into it in cavity again.
The utility model additionally provides a kind of coal powder conveying system, which includes that above-mentioned coal dust jumbo bag is opened
It is packed to set, it further include blower 6 and coal dust pot 7, venturi tube structure 8 is connect with blower 6 and coal dust pot 7 respectively.Blower 6 is preferably adopted
With roots blower, because the height of coal dust pot 7 is generally all very high, the wind pressure of common blower is not able to satisfy defeated powder ability, roots blower
Coal dust then can be smoothly transported in tens meters high of coal dust pot 7 by the high pressure of generation.Venturi tube structure 8 and coal dust pot 7 it
Between be connected with pulverized coal feed pipe 9, pulverized coal feed pipe 9 is seamless steel pipe, and the turning of pulverized coal feed pipe 9 is all made of the big elbow knot of R/d > 8
Structure, and abrasion-proof structure is welded with outside elbow, to reinforce the wearability of pipeline, to extend the service life of pulverized coal feed pipe 9.
Obviously, the above embodiments of the present invention is used for the purpose of clearly illustrating examples for clearly illustrating the present invention, and
Not limitations of the embodiments of the present invention.For those of ordinary skill in the art, above explained
On the basis of can also make other variations or changes in different ways.There is no need and unable to give thoroughly all embodiments
It lifts.Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention etc. should be included in this
Within the protection scope of utility model claims.
